In this lesson, students will learn about sampling through an investigation of rocks found in the schoolyard. This will provide a start to understanding everyday statistics. They will first collect and analyze a sample of rocks from the schoolyard and array the collected rocks by characteristics such as size, weight, and color, to see if any generalizations can be made about the types of rocks that ...

In this lesson, students will explore what happens to water as it goes from solid to liquid and back again; in addition, they will use observation, measurement, and communication skills to describe change. This lesson is the first in a three-part series that addresses a concept that is central to the understanding of the water cycle: that water is able to take many forms but is still water. This series ... Full description.
